73 Charger rearend

[Randy73]

It is a 8 3/4 and how can I tell if it is a sure-grip rearend and what gears.

Thinking it is 3.23, as the fender tag does not show anything for gears.

If untouched, it will have a tag on one of the bolts for ratio and another round tag for SG.
If neither exist then try this:
trans in neutral, one tire off the ground..can you turn the tire? Yes = open carrier.
with both tires off the ground, put a mark on the tire and a matching mark on the ground/spring/something...now turn the drive shaft by hand. How many driveshaft revs for one tire rev?

I must be getting old, forgot all about marking the wheels. I will look for the tags, thanks!!
